Observational Study
Brain Volume Changes in Patients with Acute Brain Dysfunction Due to Sepsis.
Sepsis-induced brain dysfunction (SIBD) is often encountered in sepsis patients and is related to increased morbidity. No specific tests are available for SIBD, and neuroimaging findings are often normal. In this study, our aim was to analyze the diagnostic value of volumetric analysis of the brain structures and to find out its significance as a prognostic measure. ⋯ Volumetric analysis of the brain appears to be a sensitive measure of volumetric changes in SIBD. Volume reduction in specific deep gray matter regions might be an indicator of unfavorable outcome.

Spinal cord injury (SCI) is present in around 2-4% of trauma victims. More than half of this injuries are located at the cervical region. Twenty percent of victims with cervical spinal trauma and 5% of patients with severe traumatic brain injury (TBI) will have an SCI. Cervical immobilization with rigid or semirigid collars is routinely used as prophylactic or definitive treatment intervention in general trauma care. An important adverse effect of cervical collars application is the increase in intracranial pressure (ICP) values. This systematic review and meta-analysis aim to estimate the overall magnitude of ICP changes after cervical collar application. ⋯ Heterogeneous studies of application of cervical collars as a partial motion restriction strategy after injuries have demonstrated increases in ICP in TBI patients. Increases in ICP can induce complications in TBI patients. Appropriate selection criteria for cervical motion restriction in TBI patients need to be considered.

Sleep is fundamental for everyday functioning, yet it is often negatively impacted in critically ill patients by the intensive care setting. With a focus on the neurological intensive care unit (NeuroICU), this narrative review summarizes methods of measuring sleep and addresses common causes of sleep disturbance in the hospital including environmental, pharmacological, and patient-related factors. ⋯ Where evidence is lacking in the literature, long-term sleep deprivation studies and the effects of sleep deprivation in healthy individuals are also referenced. Lastly, strategies for the promotion of sleep in the NeuroICU are presented.

Genetic Variability and Trajectories of DNA Methylation May Support a Role for HAMP in Patient Outcomes After Aneurysmal Subarachnoid Hemorrhage.
Preclinical evidence suggests that iron homeostasis is an important biological mechanism following aneurysmal subarachnoid hemorrhage (aSAH); however, this concept is underexplored in humans. This study examined the relationship between patient outcomes following aSAH and genetic variants and DNA methylation in the hepcidin gene (HAMP), a key regulator of iron homeostasis. ⋯ This exploratory pilot study offers preliminary evidence that HAMP may play a role in patient outcomes after aSAH. Replication of this study and mechanistic investigation of the role of HAMP in patient outcomes after aSAH are needed.

Randomized Controlled Trial
A Randomized Trial of Complications of Peripherally and Centrally Inserted Central Lines in the Neuro-Intensive Care Unit: Results of the NSPVC Trial.
The objective of this study was to compare the relative number of complications from peripherally inserted central venous catheters (PICC) and centrally inserted central venous catheters (CVC) in the neuroscience intensive care unit (NSICU). ⋯ PICCs and CVCs have similar numbers of complications when placed in patients admitted to the NSICU.
